T0 all lwhom t may concern Be it known that li, JAMES B. CRAWFORD, a citizen of the United States, residing at State of- Iovva, have invented certain new for VVlieelsyand I do declare the .following to .be a full, clear, and exact description of the" invention, such as will enable others skilled in the art towliicli it appertains to makeand use the saine.

This invention relates to improvements in tires and rims for vehicle wheels.

One object of the invention is to provide a resilient tire spreader and riin which are so constructed arranged that the greater the pressure applied to the tire the tighter the saine will be engaged with the rim. A

Another object is to provide a device of this kind with means for preventing it from creeping on the Wlieel.

Vith these and other objects in View, the invention co'nsists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.` A n In the accompanying drawings; Figure 1 is a side viewof a wheel showing the application of the invention; Fig. 2 is an enlarged detail longitudinal seetion of a portion of the telly, rim. and tire; Fig. 3 is a cross sectional View taken on the line .3-8 oi Fig. 2; Fig. 4 is a similar View taken on the line 4 4 ot Fig. 2; Fig. 5 is a detail pcrspective View of the inner 'and outer blocks; Fig. 6 is a plan view of the telly gripping speetive view of the detachable clamping plate employed on one end of the telly gripping and rim attaching member shown in Fig. G; Fig. 8 is a detail perspective view of the telly gripping and riin attaching member shown in Fig. 6;A Fig. 9 is a detail perspective View oi the spreader; Fig. l0 is a detail perspective View of one of the antirattling strips or cushions employed in conneetion with the telly gripping and rim :1ttaching member of the invention; Fig. ll is a cross sectional view of a modified 'term of the fastener.

Referring more particularly to the drawings 1 denotes the telly of the wheel to .which my improved rim .and tire are ap plied, said fel y preferably having a metal rim or band 1 arranged thereon as shown.

The telly 1. may he. const :ruoted ott any suitable material .and may be ot any suitable shape in cross section, said elly being here shown and is preiierably ot rectangular shape. Disposed at intervals around the band, are rim attaching members coni- I prising blocks' 2. arranged transversely across. the outer surface of the band, and each has formed integrall with one end en inwardly projeeting clamping plate or lng 3. in which is formed a. bolt hole 4,. In the outer sidei ot the block 2 is formed a reeess 5 the purpose of whieh will be hereinafter described. Adapted to rest against the open end onf. the block 5 opposite te the lng 3 is a gripping or clamping plate il having therein a bolt hole. Z with which and with the bolt hele 4i in the plate er lng 3 is engaged a clamping bolt 8, said bolt passing through a transverse bolt hole 9 in the telly l as clearly shown in Fig. 3 of the drawings. The head 10 of the bolt engages the plate or lug 3 While the nut l1 engages the plate 6 at the opposite end of the block, whereby when the nuit is tightened np on the bolt the plates 3 and G will be drawn into4 tight clamping engagement with the opposite sides of the telly thereby iiimly fastening the block 2 in position thereon.

Arranged in the recess 5 of the block 2 adjacent to the opposite sides of' the recess are packing or anti-rattling-strips 12 which are cushions of rubber or other suitable inaterial. Disposed in the recess 5 in the block and fitting closely between the packing or anti-rattling strips l2 is a bloclt having therein a renti-ally disposed screw hole 14. The blocks lil stand inside my improved. rim l5, and outside the rim opposite the blocks il are longer blocks 1G having there` trally disposed screw holes i7 with which and with the screw holesie in the biifelis 1,3 are engaged block attaching screws i8, said screws also passing through holes 19 in the rim l5. ly this structure it will be seen that the rim 15 is spaced 'trom the telly band lont firmly attached theretoat intervals around the same.

The rim 15 is in the form oi a flat metal band having along one edgr. :i tire ri ping flange '20. The opposite edge oi' t e rim isbent inwardly and then outwardlyy to forni a channeled flange 2l with whic is engaged the inner edge oit a .clenching ring 22. The elenching ring iii-.1. is bent to lt Cennti inV

ing the outer edge of said ihm e into en gogemeut with the ring 22 es s own at 28 lll-Figs. 3 und 4.

The tire includes an outer tube or member 2d which may be of tiny 'suitable shape und constructed of the seme materiel employed in. the construction of the usual form of. outer tire tubes or members and seid outertire member 24 has its inner edges'shuped to engage or it under the flange 2O and the outer portion of the clenchin ring 22 as cleerlyehown in.` Fig. 4: of trie drawings. Within. the outer member of the tire is an inner tube or spreader' member 25 in the vform of o resilient metal bund which is arched in cross section to tit the outer tire metber 24. The edges of the inner .member 25 curve outwardly and engage the inner sides of the edges of the outer member 24 n of the tre'and hold said edges ofthe outer member in lirm engagement with the flan ev Q0 and clenching ring 223 of the rim. Te edges of the tire are provided with notches Q6 while the edges -of the member 25 are provided with similar and re steringnotches 27 with which the ends of t e outer blocks 15 are engaged, said blocks thus firmly holding the tire in position and preventing the seme from creeping on the rim of the wheel. By constructing und arranging the tire and the rim ae herein shown and described, it will be scen that the greater the pressure or load applied to the tread of the tire the more the edges of the spreader will be 'forced eport and the ti hter the edges of the tire 24 will be force into engagement with the flange Q0 und clenching ring 22 of the rim. It will oleo be noted that the tire when constructed as herein shown and described will be ractically puncture proof and will possess t ie same or more resiliency than the usual form of pneuf matic tire. By attaching the rim of the tir to the folly of the wheel as herein shown und described, it will' be seen that in orderto remove the 'rim and tire it is necessary simply to uuecrew the nutsll from the bolts of 'tho-rim attaching blocks Z, whmeupnn claiming platee t3 muy be disengaged from the ends of the bolts end the inner end 'outer blocks, together with the rim undtire, maybe slipped'oll from He rim, the blocks 13 sliding out of the open ends of the recesses 5 in the blocks as will be reodily understood.

ln ltlig. ll of the drawings-i is shown u modilied form of trim Q8 both edges of which are turned .iutwnrdly in two slightly conmeinte verging flanges 29 with which theiedgesl of the outer member 30 of the tire are cn-y gaged. The tire in the modified form of the invention is provided with 'an inner tube or spreader 31 and is otherwise constructed in theseme nanner as the tire `rnodiied form of the tireis appledfand fastened to the folly of the wheel ,in'the' same manner as the tire. In either form of this device the parte m assembled by lirst placing the blocks in upon the rim, whose left-hand flange 9 or the outer edge of whose clenching ring 22 will ut this time be A bent outward, then preferred form; of the placing the rubber tire or tread over the spreader and put-ting these members in place around the rim with their n0tches"`in enagement with the outer block 16, and nelly bending 'the outer edge of the ring 22 or the left hand flange 29 inward so that the parts stand respectively as sn in Figi. 3 und 1L While it is truethat o worn trend and its spreader muy be4 re laced by machinery, it is not .contempla thn't the 'average automobilist will possess machinery. butin case of accident he/merely sl o new `rirn and its tire onto the wheel an secures it' in place b "my preferred menne aabove described an with which the inner bloclial 13 coact very nicely-as has been en plairied.

From the foregoing description taken lr connection with the accompanying dm ings, the construction and operation ol thtinvention will be readilyluuderstood with out requiring a more extended explanution.

Various changes inthe form, proportion and the minor detailsof construction maybe resorted to Awithout departing 'from tb principle dr sacrificing any ofmthe r tages of this invention as defined claimed.

. Having thus articularly described my invention, what Pclam is':

1. Theicombination with an arched Head. and an arched metallic spreader in de tlv-:5 tread, `the edges of these elements lui' np registering notches' of a rim havin a chan- )ai of a rim having a channel Within which the 'edges of the tread are embraced, and a block extending acrosssaid rim and fitting in said notches.

3. The combination with an arched tread, and an arched metallic spreader inside the tread, the edges of these elements having registering notches, 'a rim having a channe within which the edges of the tread are embraced, a blockextending across the outer face of the rim through such notches and .'.ith its extremities engaged by the flanges of the rim, a second and shorter block extending across the inner face of the rim,l
